JOHN J. ORONIN, OF MANcHEsTER, NEw HA'MPs iRE, ASSIGNOR OF- oNE- H LE TO HARRY E. PARKER, or MANCHESTER, NEW HAMPSHIRE.

To aZZ whom it may cono ern:

Be it known that I, J OHN J. CRONIN, acitizen of the United States, and a resident of Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in Ring-Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to ring-spinning apparatus; and it has for its object the production of novel means for reducing wear on the ring and permitting the employment of higher spindle speeds.

In the course of my study of ring-spinning apparatus 1 have found that the traveler wears the inner flange of the ring very rapidly when the spindle speed is raised much above about ment.

eight thousand revolutions per minute, such wear in the first instance being due to the centrifugal force exerted upon the traveler.

When the spindle speed is raised, the wear increases rapidly and also unevenly, this being due apparently to the fact that the traveler tends to bear harder at times on the inner portion of its path on the ring, probably varying friction generated. I have foundv that while at the average speed hereinbefore mentioned the rings will last many years an increase of speed to, say, ten or eleven thousand revolutions not only'burns ofi the travelers more frequently, but causes such wear on the rings that they will not last longer than about two years.

In my present invention I have provided means whereby the ring may have a slight and free axial lifting movement with relation to the ring-rail, so that when the yarn pull increases the ring will give to it. With this construction I am enabled to use high spindle speed without wearing the ring or burning off the traveler. arranged that it always maintains a fixed position with relation to the ring moving .in unison therewith, and the ring is prevented from having any-rotativ-e or lateral move- The ring is thus always centered with relation to the spindle, and highly-efficient results are obtained.

The various novel features of my invention Specification of Letters Patent. 7

Application filed December 16, 1904:. Serial No. 237.064.

The traveler-clearer is so RING-SPINNING APPAlRATUS.

Patented Dec. 5, 1905.

will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top or plan view of a portion of the ring-rail of a spinning apparatus with a ring and ring-holder connected therewith in accordance with my invention. Fig. 2 is a diametral section on the line 2 2, Fig.1; and Fig. 3 is an enlarged sectional detail on. the line 2 2.

I have herein shown the spinning-ring 1 of the well-known double-flanged'type and provided with a'traveler 2 of usual construction. The ring-holder herein shown is in the main also of well-known structure, it being made of sheet metal and comprising a fiat base 3, having a circular opening 4, through with in a manner familiarv to those skilled in the art.

In -my present invention I connect the ringholder in a novel manner with the rin -rail 7,

so that the ring-holder and connected ring may have a limited axial movement. To this end-I provide the base 3 with apertures 8, (shown as diametrically opposite each other,)

and through said apertures headed connections arefreely passed and fixedly attached to the ring-rail. The headed connection is herein shown as a stud 9, having a head 10 and reduced in diameter and threaded below a shoulder 11, as clearly shown in Fig. 3. The distance between the under side of the head 10 and the shoulder 11 is slightly greater than the thickness of the base 3 of the ring-holder,

the studs being passed freely through the apertures 8 in the base, and then the threaded ends are passed through holes in the ringrail, the shoulders 11 resting thereon and being held securely and rigidly in place by suitable nuts 12. When the ring-holder. is thus connected with the ring-rail, it and its rigidlyattached ring 1 can have a limited rising or axial movement on the studs, (see dotted lines, Fig. 3,) but no rotative or lateral movement. The clearer 6 being in fixed relation to the ring partakes of any rising or falling movement thereof, and hence is always in proper position to clear the traveler. In operation if the drag or pull on the yarn increases it acts to lift the ring slightly, and thereby the strain of the traveler on the ring is eased, the ring returning to normal position when the normal pull is restored. The fixedly-connected ring-holder acts as a balance to the ring and steadies it in its axial movement, while the studs 9 prevent any rotative movement of the ring and also maintain it centered with relation to the spindle S, Fig. 1.

It is essential to the proper operation of my invention that the traveler-clearer shall always maintain a definite fixed relation to the ring, and herein this is secured by mounting the clearer on the ring-holder, which latter partakes of every movement of the ring.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A spinning-ring, a sheet-metal holder with which it is rigidly connected and adapted to be attached to a ring-rail, a travelerclearer on the holder, and headed attaching members fixedly mounted in the ring-rail and passing loosely through the holder, to permit limited axial movement of the ring and holder in unison relatively to the ring-rail while preventing lateral and rotative movement.

2. In spinning apparatus, a ring-rail, aspinning-ring, a sheet-metal ring-holder having a traveler-clearer and provided with means to engage and rigidly hold the ring, said holder having a plurality of openings in its base, and headed attaching members fixedly mounted in the ring-rail and having their shank portions below the heads extended freely through the openings in the holder, to permit limited vertical or lifting movement thereof in unison with the ring while preventing lateral and rotative movement.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
